Application filed September 13, 1918.

To all whom it may concern:

Be it known that I, Ax'roNIo DAWER, a citizen of the United States of America, residing at New York city, in the county of New York and State of New York, have invented new and useful Improvements in Graphophone Attachments for Moving Pictures, of which the following is a specification.

This invention relates to sound reproducing and recording mechanism.

The invention pertains to the class of sound producing and picture displaying apparatus wherein ideas suggested in the picture displayed will be accurately communicated and supplemented by articulate utterance or other sounds which have been previously transcribed or recorded upon a suitable record or tablet.

The invention is intended to be used at the time of taking the picture or subsequently, and is designed so that at either time, the picture and corresponding sound Will be synchronously brought together.

In the taking of moving pictures, it is sometimes impossible to record sounds characteristic of the picture and I wish therefore, to emphasize those features of the invention which will properly permit of the first taking of a picture and a subsequent recording of sound, both in proper synchronism.

Another object of the invention resides in the provision of mechanism for supporting a plurality of cylinders upon which the sounds are to be transcribed and recorded, and means for operatively setting one of the records in recording position when the other record has been fully utilized for recording purposes.

Another object of the invention resides in the provision of mechanism for transcribing and producing sound and means whereby a particular portion of a picture film can be properly mated with or identified by a corresponding portion of the sound record so that should film be broken at places, it may be repaired and by simply adjusting the recording or transmitting mechanism, the desired harmonious opera tion of parts can be continued without any inconvenience on part of the operator and without causing confusion.

The invention comprises a suitable support or table 18, provided at its ends with vertical standards 19 and 20, and an inter mediate standard 21. J ournaled in the said standards 19 and 20, are shaft-s 22 and 23, which are normally arranged in parallel relation and provided with sections operatively connected with each other by universal joints 24, whereby said shafts may be adjusted from their normal positions for a purpose to be hereinafter explained. Each of these shafts supports a mandrel 25, upon which is adapted to be mounted a wax cylinder 26, or the like upon which sound is adapted to be recorded in a manner to be hereinafter fully explained. The opposite ends of these shafts are normally supported in sliding bearings 27. which when adjusted to one position are adapted to permit the shafts to be swung laterally for the purpose of applying the records to or removing the same from said mentioned mandrels. I do not wish to limit myself to this precise arrangement as many obvious mechanical contrivances can be substituted therefor that will satisfactorily permit of the application of the records to or removal of same from their respective mandrels 'as the occasion necessitates.

The said shafts 22 and 23, freely extend through the hubs of driven gear wheels 28 and 29, and as illustrated these wheels are swiveled in the standard 19, and each is provided at one side of said standard with a clutch element 30, which is adapted to co-act with a sliding clutch element 31, on the mandrel shaft. The said elements 31, are keyed to rotate with the mandrel shafts and are adapted to remain stationary when the elements 30, are disengaged from their mating elements 31. The sliding clutch elements are operattively connected with bell cranked levers 32, supported from the standard 21, and as illustrated said levers are provided with rollers 33, which travel in cam grooves 34, formed in the side faces of worm gears 3535. These gears are operatively supported from brackets 36, which rise from the table 18, and the same are in mesh with driven worms 37, on shafts 3838. The inner ends of these shafts are provided with bevel gear wheels 39, which intermesh with a drivin gear wheel 40, the latter being journaled 1n the standard 21, and provided with a gear wheel 41, intermeshing with a gear wheel 42, on a shaft 43. The said shaft 43, is provided with a gear wheel 44, which meshes with an idle gear 45, the latter meshing with the gear wheel 29, of the mandrel shaft 23. A power shaft 46, adapted to be driven by a suitable motor 47, is provided with a pulley 48, and as illustrated said pulley is connected by a belt 49, with a similar pulley 50, on a power transmitting shaft 51. This shaft carries a power transmitting gear wheel 52, which meshes with an idle gear wheel 53, at one side and a small gear wheel 54, at the opposite side, the former having intermeshing engagement with the wheel 29, of the mandrel shaft 23. The gear wheel 54, meshes with an idle gear wheel 55, and the latter in turn meshes with the mentioned gear wheel 28, of the mandrel shaft 22. Through this arrangement it obviously follows that motion having been transmitted to the shaft 51, as just described power will be conducted through the gear 45, to the shaft 43, and to the intermeshing gear wheels 41 and 42. Power is therefore supplied to the worm shafts 38-38, and motion set up in the cams 35-35, for a purpose to be presently explained.

In addition to the transmission of power through the instrumentalities described above power is taken from a pinion 56, which intermeshes with an idle gear wheel 57, and as illustrated the latter intermeshes in the direction of the next adjacent sound record as shown in Fig. 2. For this reason the shafts 60 and 61, are disposed in parallel relation with the mandrel shafts 22., and 23, whereby they will be arranged directly at one side of the sound records. Keyed to the shafts 60 and 61 respectively are sliding clutch elements 64 and 65, whichare adapted to respectively mate with similar clutch elements 66 and 67 carried by the mentioned gear wheels 58 and 59. At the opposite ends the said shafts 60 and 61 freely pass through the hubs of gear wheels 68 and 69, provided with clutch elements 70 and 71, which are adapted to mate with sliding clutch elements 72 and 73, on said shafts. These gear wheels 68 and 69, are in mesh with a large power transmitting gear wheel 74, which is provided on one side with a cam groove 75, having operative connection with an actuating arm 76. The recording instruments 6.2, are each mounted to tilt in a supporting frame 77, which rises from a nut 78, received by the next adjacent worm shaft of the mechanism and asillustrated the said instruments are provided at their lower ends with weighted portions 79, which operate to gravitationally hold said instruments in perpendicular positions. Squared shafts 80, are journaled in the standards 20 and 21, and are free to rock therein and as shown each of said shafts supports a sliding actuator 81, having a finger 82, extended through a slot 83, in the frame 77, of the next adjacent recording instrument 62, and the same is adapted to bear against said instrument at one side thereof as clearly shown in Fig. .13. Depending from the shafts are fixed arms 84, which are operatively connected with the actuating arm 76, (see Fig. 6), The slide 81, of one of the recording instruments is provided with a trip. 85, which is disposed in the path of projections 86 and 87, on rockers 88 and 89, said rockers having connection respectively with levers 90 and 91, which are mounted to rock from a bracket 92, the latter rising from the table 18. One of these levers is connected through a controlling rod 93, with a clutch actuator 94, which is operatively associated with the keyed clutch elements 72 and 73, at the right of Fig. 2. The other lever has operative connection through a rod 95, with an actuator 96, operatively connected with the clutch elements 64 and 65, at the left of Fig. 2.

The table 18, supports a scale bar 97 which is arranged between the mandrels 2525, as plainly indicated in Fig. 2, and co-acting with the graduations thereon are pointers 98, carried by the frames 77, of the recording instruments. The worm screws 60 and 61, are respectively threaded in re versed directions in order that during movement of one of the recording instruments in one direction the other of said instruments is in course of movement in an opposite direction. As illustrated the scale bar 97, has

graduations at one side ranging from to 160, while at the other side the graduations are arranged from 170 to 320. In this mannerand through the fact that the recording instruments operate reversely the scale surface at one side of the bar 97, is simply intended as a continuation of the scale surface at the other side of said bar, hence the multiple mandrel arrangement which operates to receive a plurality of records adapted to be successively operated upon. In other words after one of the recording instruments has operated over the full length of the record, it is automatically thrown out of operation and is caused to traverse its worm screw in a returned direction while the other instrument is moved into recording relation with its record. In view of this operation and arrangement of parts it will be appreciated that the operation of recording sound can be carried on without any material interruption during the period of taking the picture.

The operation above described is permitted through the fact that the trip 85, is adapted to engage with the projection 86, of the arm 89, on the limit of its movement in one direction and thereby release the clutch elements 64 and 65, from their mating elements 66 and 67, and cause, the elements 72 and 73, to be thrown into operation with their mating elements and 71. The reversal of this order of operation is, of course, set up when the trip 85, engages with the projection 87. In this manner motion will be imparted to the worm screws first, in one direction and then in an opposite direction, in order to permit the sound receiving records to be successively brought into operation with their respectiverecording instruments.

The shaft 98', on which the gears 40 and 41, are mounted is provided with a bevel pinion 99, in mesh with a. similar pinion 100. on a shaft 101, the latter having a crank 102, whereby the shaft 101, can be revolved manually and power transmitted to the shaft 98'. the latter is also provided with a gear wheel 103, which meshes with a gearwheel 104, forming a.part of the gear wheel 74:. The motor 47, is operatively connected by clutch mechanism 105, with a manual control lever 106, which may be operated to throw the motor in and out of operation respectively.

This mechanism, when combined with the means for manually transmittmg power to the shaft 98', permits of a manual resetting of the sound instruments 622, should the picture film be brokn in any particular part during the picture exhibiting operation. The requisite positioning of the recording instruments with respect to their records is deter mined by providing graduations 107, along one edge of the film 108, as shown in Fig. 16, and providing said graduations with a co-act-ing pointer 109. The graduations on the film strip are, of course, arranged in exact conformity with those on the mentioned scale bar 97.

It is, of course, understood that the mechanism is designed for use both for the pur" pose of recording and re-producing sound and while only a recording instrument has been shown, it obviously follows that any suitable well-known form of reproducing instrument could be substituted therefor.

I Wish also to state that any suitable wellknown means for the amplification of sound can be connected with the recording or reproducing instruments. As such does not form any particular feature of the invention no detail or elaboration thereof is made. I wish further to state that any suitable indicating device may be incorporated together with the instrumentalities previously described, in order that at the finish of the record it may be visually or audibly announced to the one in charge.
